Nattokinase reduces liver cancer growth
Nattokinase Crude Extract Inhibits Hepatocellular Carcinoma Growth in Mice.
High relevance observed in findings
We assessed the effects of nattokinase crude extract (NCE) on hepatocellular carcinoma (HCC) growth in mouse models. Our findings revealed that NCE significantly improved survival rates among treated mice and resulted in decreased tumor size. The extract lowered levels of specific proteins associated with cancer progression, further indicating its potential as a treatment option. Overall, we found that NCE leads to both enhanced survival and reduced tumor growth in HCC-bearing mice.

Effective novel liver fibrosis treatment
Precisely Controlling the Activation of an Iron-Locked Drug Generator in the Liver Sinusoid to Enhance Barrier Penetration and Reduction of Liver Fibrosis.
High relevance for liver fibrosis
We explored a new approach to treat liver fibrosis using a combination of a nanosized iron-locked drug generator and oral nattokinase therapy. This innovative method allows drugs to bypass barriers in the liver, ensuring they reach damaged areas effectively.

By administering iron chelator deferasirox alongside, we witnessed improved drug activation precisely in the liver, leading to significant antifibrotic effects. Remarkably, this strategy not only reversed liver fibrosis but also minimized the toxic effects of iron in the liver.

Our findings could pave the way for similar treatments targeting liver diseases in the future.

No more pain
Welcomed Relief! I'm a very active 62-year-old male in good health and physical condition. However, I recently suffered severe "burning" pain in the calf muscles of both legs. My doctor informed me that I had developed P.A.D.s (peripheral vascular disease). Though I always walked 3-5 miles daily, the condition made it extremely painful. The doctor advised me to keep walking, hoping the pain would subside. A relative suggested I try Doctors Best, Best Nattokinase. After taking one capsule in the morning and another in the evening, I went for a 4-mile walk the next day and experienced "No more burning pain"! I continue to take two capsules daily.

Symptom-free now
Cleans the arteries! As someone with a history of heart disease symptoms and wishing to avoid coronary bypass surgery, this supplement has been crucial along with vigorous cardio exercise. I was terrified at one point and prepared for the worst. Fortunately, I learnt about fibrinolytic enzymes like nattokinase. By reducing fat intake and taking these supplements, it has worked well. Today, I am symptom-free, and I trust the quality of Doctors Best products.

Relieves leg pain
Following a recommendation for my DVT (deep vein thrombosis), I took Nattokinase alongside anticoagulants. After a year of treatment, despite managing the condition, side effects like inflammation arose. Fortunately, after taking Nattokinase, the redness and pain in my leg decreased significantly within days, and now my mobility has improved dramatically.

Improved stamina
Three years ago, I could only work four hours per day due to heart pain and necessitated Nitroglycerin. After starting Nattokinase to help with Lyme disease, I noticed significant improvement—working eight hours with no issues. It has replaced aspirin for me, alleviating stomach irritation. I consider Nattokinase to be miraculous and beneficial for my everyday productivity.

Stability achieved
After having a stroke, the doctors wanted me on warfarin, which I was reluctant to take. However, a cousin, a lab manager, suggested nattokinase to prevent my blood from becoming sticky and forming clots. I have used it for several years; it completely eliminated the light-headedness I was experiencing. I currently take two pills a day, keeping everything stable. It’s not a blood thinner, so there's no risk of excessive bleeding or the need for ongoing kidney or liver tests. I wouldn't be without it.
